The purpose of the study is to find the effects of different growing site conditions on trees with the vessel features in the woods of Quercus ilex L. growing in different regions through Turkey, and to evaluate the results in respect of forestry. A total of 102 wood samples were collected from 102 sampling plots (as 20 m × 10 m plots) in 9 distribution areas in Turkey. Environmental, climate and stand data were obtained for each plot. Standard wood anatomical studies were performed. The results show that, while vessel element lengths are almost stable in all regions, the most …

The incidence rate of occupational accidents is an important indicator of occupational safety performance. The aim of this study was to classify the similarities and differences among 23 European Union (EU) countries along with Turkey in terms of various occupational accident evaluation criteria. This was achieved using the k-means clustering method on data from the forestry and logging sector between 2008 and 2017. The occupational accident assessment criteria used in the study include the nonfatal male accident incidence rate, the nonfatal female accident incidence rate, the total (male + female) nonfatal accident incidence rate, and the total (male + female) …
